Filed April 19, 1941 Richard Jo 2 Q Patented Mar. 31, 1942 UNITED STATES ()FFICE GREENCORN TRIMMER Richard L. Joyce, Ballsville, Va. Application April 19, 1941, Serial. N5. 389,444.

3 Claims.

The object of'my invention is to provide a new and useful green corn trimmer by means of which green corn can be conveniently trimmed or shelled from the cob; and to provide a device which is readily adjustable to ears of corn of different length.

It is also an object of my invention to provide a device of this character which can be manufactured at a reasonable cost and which can be conveniently operated manually.

I attain these and other objects of my invention by the device illustrated in the accompanying drawing, in which- Figure 1 is a front plan view of my invention, an ear of corn being indicated by dot and dash lines;

Fig. 2 is a side elevation of my invention;

Fig. 3 is a transverse section on line 3-3 of Fig. 1 with arm I9 and bar I4 in closed position; and

Fig. 4 is a section on line l4 of Fig. 1 with the bottom I9 and bar I4 in open position.

Like characters of reference designate like parts in each of the views.

Referring to the accompanying drawing, I provide a main frame consisting of parallel bars I, integral and arcuate end bar 2 and overlapping top bars Ia. The base bar 3 carries a cob cup 4 and both of said members are secured to the arcuate end bar 2 of the main frame I by suitable securing means such as bolt 5, and tongue 6. A transverse bar 7 near the top of main frame I is affixed to or integral with the main frame. A handle 8 is rigidly afi'ixed to one side of the main frame, near its upper end, as shown in Figs. 1, 3 and 4. Extending through the top transverse bars Ia of the main frame is a shaft 9 on which is mounted a control spring Ill, the upper end of which spring abuts against the top end Ia of the main frame I, and the lower end of which spring abuts against the upper end of the enlargement I2 of the cylindrical shaft 9. cylindrical shaft section I2 is longitudinally slidable in a corresponding aperture I311 in the transverse bar l. Member I2 terminates in corn cob engaging tines I3, which are adapted to project into the upper end of a corn cob C, the lower end of which is seated in a cob cup 4.

I also provide a corn-trimming blade I4 affixed to the lower end to the cylindrical bar 2|, which is rotatably mounted in the base bar 3. The upper end of the corn-trimming blade I4 is affixed to the cylindrical bar 22 which is rotatably mounted in the transverse plate 'I and terminates in a screw-threaded end on which an adjusting This enlarged wing-nut I5 is mounted. Wing-nut I5 bears against the washer 23 which in turn bears against a spring I6. The lower end of spring I6 abuts against thetop surface of transverse bar "I and thus tends to raise the corn-trimming blade I I to prevent lower end of the blade contacting with the cob cup 4.

A curved 'bar I9 is affixed by rivets I8 to the upper end of the corn-trimming blade I4. This arcuate blade I9 is curved to avoid contact with the corn cob if a long ear of corn is inserted, and is bent in offset direction at 20, and which also functions as a stop element to contact with the frame I, and terminates in the handle portion II, which may be grasped to swing and control the position of the cutting edge Ma of the corntrimming blade I4, a indicated by the arrows in Figs. 3 and 4, which show two different positions of the blade I4.

In operation, the shaft 9, I2 is raised suficiently to permit insertion of the lower end of the ear of corn in the cob cup 4, and the upper end of the ear of corn is then engaged by the tines I3 carried on the lower end of the enlarged shaft I2. The device is held in one hand by the handle 8, one finger of that same hand engaging the handle portion I! of the bar I9 which controls the position of the corn-trimming blade Ill. The corn cob is rotated by turning the crank II, which in turn rotates the shaft 9, I2 and tines I3, which engage the ear of corn, whereby the kernels of the ear of corn can be quickly and conveniently trimmed or shelled manually.

What I claim is:

1. In a green corn trimmer, the combination of a main frame, a cob cup carried by the bottom of the main frame, a cylindrical shaft longitudinally slidable in the transverse bars at the top of the main frame, corn engaging tines carried by the said shaft at its lower end, a crank affixed to and adapted for rotating the shaft, a spring tending to hold the shaft in its lowermost position, a handle afiixed to the main frame for holding same, a corn-trimming blade extending longitudinally of the main frame and swingably mounted on same, a bar affixed to the said corn trimming blade near one end and terminating in an offset handle in proximity to the handle aflixed to the main frame, whereby the position of the corn trimming blade can be controlled by one of the fingers of the hand which grasps the handle affixed to the main frame.

2. In a green corn trimmer, the combination of a main frame, a cob cup carried by the bottom of the main frame, a cylindrical shaft longi tudinally slidable in the transverse bars at the top of the main frame, corn engaging tines carried by the said shaft at its lower end, a crank amxed to and adapted for rotating the shaft, a

handle afiixed to the main frame for holding.

tudinally slidable in the transverse bars at the top of the main frame, corn engaging tines carried by the said shaft at its lower end, a crank affixed to and adapted for rotating the shaft, a spring tending to hold the shaft in its lowermost position, a handle affixed to the main frame for holding same, a corn-trimming blade extending longitudinally of the main frame and swingably mounted on same, a bar affixed to the said corn trimming blade near one end and terminating in an ofiset handle in proximity to the handle aflixed to the main frame, whereby the position of the corn-trimming blade can be controlled by one of the fingers of the hand which grasps the handleaffixed to the main frame, a spring tending to hold the corn-trimming blade in its uppermost position whereby to avoid its striking the cob cup.
